I am trying to explain a mathematical point that is used for comparison such that all values are compared to it, like a "frame of reference". I've also thought of "pivot of comparison". Are any of these two correct or is there a better expression for this?

Or how about a benchmark, defined as:

A standard by which something is evaluated or measured.

A reference point.

How about reference point ...

a basis or standard for evaluation, assessment, or comparison; a criterion.
